How deep and wide must my house footings be?
That depends on the number of stories the house will be. A minimum of 12”inches deep for all footings and the width will be determined by the amount of stories, 12” inches for a single story, 15” inches for a two story and 23” inches for a three story. This is based on a soil bearing capacity of 1500(psf). Other factors such as brick siding and type of foundation walls could change requirements to slightly larger widths.
